How to use this guide

Basic principles of application 116 for ECL Comfort 110
If the measured flow (DHW) temperature (S3) is lower than the desired DHW
temperature, the motorized control valve (M1) is opened gradually and vice versa.
The return temperature (S4) to the district heating supply should not be too high. If so,
the desired flow temperature can be adjusted (typically to a lower value) thus resulting
in a gradual closing of the motorized control valve, i.e. the return temperature will
decrease.
The circulation pump, P1, is ON when the desired flow temperature is higher than 20 °C
(factory setting) or the actual flow temperature (S3) is below 10 °C (factory setting).
Furthermore, a flow switch (FS) signal (terminals 11 + 12) can be applied in order to heat
the DHW separately on DHW demand (DHW tapping, DHW draw-off).
If a supply temperature sensor S2 is connected, the proportional band Xp is adapted
to the actual temperature in order to avoid control instability. In addition, an idle
temperature for the supply temperature can be maintained to minimize the heat-up
time for the DHW.
